Kupita patsogolo kwaposachedwa pazoletsa za EU PFAS

Pa November 20, 2024, akuluakulu a boma la Denmark, Germany, Netherlands, Norway, ndi Sweden (otumiza mafayilo) ndi ECHA's Risk Assessment Scientific Committee (RAC) ndi Socio Economic Analysis Scientific Committee (SEAC) anaganizira mozama maganizo a sayansi ndi luso la 5600. adalandira kuchokera kwa anthu ena panthawi yokambirana mu 2023, ndipo adatulutsa zomwe zachitika posachedwa panjira yoletsa perfluoroalkyl ndi polyfluoroalkyl zinthu (PFAS) ku Europe.

Malingaliro opitilira 5600 awa amafunikira kuti wopereka fayiloyo aganizirenso, asinthe, ndikusintha zidziwitso zomwe zaletsedwa mu PFAS. Zinathandiziranso kuzindikira ntchito zomwe sizinatchulidwe mwatsatanetsatane mu lingaliro loyambirira, zomwe zikuphatikizidwa pakuwunika komwe kulipo m'dipatimenti kapena kugawidwa ngati madipatimenti atsopano ngati pakufunika:

Kusindikiza ntchito (ma polima opangidwa ndi fluorinated amagwiritsidwa ntchito kwambiri m'magawo ogula, akatswiri, ndi mafakitale, kuphatikizapo zisindikizo, mapaipi a mapaipi, ma gaskets, zigawo za valve, ndi zina zotero);

Zovala zaukadaulo (PFAS yomwe imagwiritsidwa ntchito m'mafilimu ochita bwino kwambiri, zida zamankhwala zosaphimbidwa ndi zamankhwala, nsalu zakunja zaukadaulo monga nsalu zopanda madzi, etc.);

Ntchito zosindikizira (zigawo zokhazikika ndi zinthu zomwe zimagwiritsidwa ntchito posindikiza);

Ntchito zina zachipatala, monga kulongedza ndi zowonjezera za mankhwala.

Kuphatikiza pa kuletsa kwathunthu kapena kuletsa kwanthawi yochepa, ECHA ikuganiziranso zoletsa zina. Mwachitsanzo, njira ina ingaphatikizepo mikhalidwe yomwe imalola PFAS kuti ipitilize kupanga, kugulitsa kapena kugwiritsa ntchito, m'malo moletsa (zoletsa zina osati kuletsa). Kulingaliraku ndikofunikira kwambiri paumboni wosonyeza kuti kuletsa kungayambitse zovuta zambiri pazachuma. Zolinga za njira zina zomwe zikuganiziridwazi zikuphatikiza koma sizimangokhala:

Battery;

Mafuta a cell;

Electrolytic cell.

Komanso, fluoropolymers ndi chitsanzo cha gulu la zinthu perfluorinated zomwe zimakhudzidwa kwambiri ndi okhudzidwa. Kukambiranaku kudakulitsa kumvetsetsa za kupezeka kwa njira zina zogwiritsira ntchito ma polima awa, njira zaukadaulo ndi bungwe kuti achepetse mpweya wawo wachilengedwe m'chilengedwe, komanso zomwe zingachitike pazachuma pakuletsa kupanga kwawo, kumasulidwa kwa msika, ndikugwiritsanso ntchito. aganizidwenso.

ECHA iwunika kuchuluka kwa njira iliyonse ndikuiyerekeza ndi zoletsa ziwiri zoyambirira, zomwe ndi kuletsa kwathunthu kapena kuletsa kwanthawi yochepa kuti asakhululukire. Zonse zomwe zasinthidwazi zidzaperekedwa ku makomiti a RAC ndi SEAC kuti awunikenso. Kukula kwa malingaliro kudzalimbikitsidwanso mu 2025 ndipo kutulutsa malingaliro olembedwa kuchokera ku RAC ndi SEAC. Pambuyo pake, zokambirana zidzachitikira pamalingaliro okonzekera a komiti ya alangizi. Izi zipereka mwayi kwa onse omwe ali ndi chidwi kuti apereke zambiri zokhudzana ndi chikhalidwe ndi zachuma kuti SEAC iganizire zomaliza.
